Samsung SyncMaster 931BF 19" Monitor. Screen was working fine. But now after raising the resolution past 1280X1024, the screen wouldn't display anything.
I tried it on my older monitor, a CRT. It worked fine, at all resolutions. When I connected back to the Samsung, I saw that the screen was displaying but it was just VERY dark and dim. I tried pushing the button for brightness, and I saw a faint box with the words "Brightness not Available." The Auto Adjustment Feature Button works but it doesn't solve the darkness problem.
I've tried connecting through VGA (Analog) and Digital (DVI). None work on the Samsung. The older CRT model only has an analog output and it worked.
Help please. THanks in advance.

Have you updated any software, drivers, any hardware changed? Have you reseated the monitor cables? Changed the resolution? When it's in safe mode the resolution is different, you can check it in Display Properties, by right clicking an open area on the disktop and selecting Screen Resolution, then boot to normal desktop, check screen resolution.

Hello,
This generally means you have the display resolution set higher then the monitor can support. To fix this press F8 after you turn the computer on. You may have to press it a couple times before the windows loading screen. A black menu will come up. Select safe mode. Your PC will load into safe mode with minimal drivers and settings. Go to the control panel and select display. Change your screen resolution to something lower then the setting is is at right now. If your screen is 19" or smaller try a setting of 1024x768 for starters. If its 20" or higher try 1280x1024 for starters.

The resolution of the display is set higher than what your monitor can support. Boot into Safe Mode, Right click on display, Properties, Settings, at Screen resolutions select the default resolution of your monitor 1024x768 or 1280x1024, depending on the version .

The monitor (19-inch, non-flat screen, 0.24 dot pitch) presented a more than acceptable image, even at its maximum supported resolution (1600X1200 @ 75Hz). We settled on a more reasonable 1280x1024 @ 85Hz as our preferred setting. According to the documentation, the recommended resolution is 1280x1024 @ 75Hz .Many of the newer LARGE monitors are limited to 60Hz and/or a larger dot pitch...So..look for a low dot pitch(below 0.27) and the ability to run at 1280X1024@75Hz . Passed that, the size is up to you.

You should reboot your computer. Immediately after you see the BIOS splash screen (Dell, Acer, HP, etc...) start pressing the F8 key 2 times every second. If you're quick enough, you'll get the Windows boot menu. When you see the menu, select "VGA Mode". This will boot Windows with minimal video settings which are compatible with all modern monitors.

Once Windows loads, right click on the desktop, select Properties, go to the Settings tab, and begin sliding the resolution bar up from 800x600 and clicking Apply. After each change, it'll ask you if you want to keep the settings. If you can still see the screen, click Yes. If you get to a setting where your monitor goes black and says "mode not supported", then wait 15 seconds and it'll revert to the last mode that worked. Leave it there.

Sounds like you have an LCD monitor. LCD monitors look best in their native resolution. Yours must be 1280x1024. You need to (assuming this is a Windows PC) right click on the desktop and choose Personalize, Display Settings (Vista) or Properties, Settings (XP or older). Set the slider to 1280x1024. It'll confirm the change and then the message should never reappear.
